5. "An Appendix to a paper on the Nervous Ganglia of the Uterus, 

 with a further Account of the Nervous Structures of that Organ." 

 By Robert Lee, M.D., F.R.S. 



After premising a short history of the opinions of Galen, Dr. 

 William Hunter, Mr. John Hunter, Professor Tiedemann, Professor 

 Lobstein, and Professor Osiander, relative to the existence, course, 

 and enlargement of the nerves of the uterus, the author adverts to 

 his own researches on this subject, which commenced with his dis- 

 covery, in April 1838, of the trunk of a large nerve accompanying 

 the uterine vein, and of the great nervous plexus with which it was 

 continuous. Of this discovery he gave an account to the Royal 

 Society in a paper read on the 12th of December of the same year. 

 In a subsequent paper, he described some large nervous ganglia* 

 situated at the neck of the uterus ; and in the present appendix he 

 describes other nervous structures of still greater size which pre- 

 sented themselves to him, on a still more complete dissection which 

 lie made of a gravid uterus at the full period of gestation. It ap- 

 pears from the results of these dissections that the human uterus 

 possesses a great and extensive system of nerves, which enlarge du- 

 ring pregnancy, along with the coats, blood-vessels, and absorbents 

 of that organ, and which after parturition resume their original con- 

 dition. It is chiefly through the influence conveyed by these nerves 

 that the uterus is rendered capable of performing its various func- 

 tions, and by which sympathies are established between it and other 

 parts of the system.
